Title: Control device for diesel engine
Inventor: AIYOSHIZAWA EIJI
IPC: F02B37/12
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To reduce NOx and particulate matter simultaneously by controlling fuel injection pressure and supercharging pressure so that an ignition delay period becomes larger than a fuel injection period as detecting the actual fuel injection period and the ignition delay period. SOLUTION: In a diesel engine conducting low temperature premixed combustion, fuel injection timing is computed from a sensor 61 detecting fuel injection start timing and termination timing from a fuel injection valve, a sensor 62 detecting the combustion start timing of the injected fuel, and the detection values of the fuel injection start timing and the injection termination timing. A ignition delay period is computed from the detection values of the fuel injection start timing and the combustion start timing. When the ignition delay period is shorter than the injection period, fuel injection pressure is pressure- increasing corrected so that the injection period of the fuel becomes shorter. When a supercharger is provided, also the supercharger is pressure-decreasing corrected so that the ignition delay period becomes longer.
